Application filed March 17, 1910. Serial No. 550,043.v

To all whom it may` concem:

Be it known that I, ConNELi-Us B. ConcoRAN, a citizen of the United States, residing in the boroughof Bronx, city of New York, in the county ofvNew York and State of New York, have invented certain new and useul Improvements in Type-Writing w ich the following isa specification. This invention relates` to the platen and coperating devices in a typewriting ma chine, for andling tle sheets of paper, and

to means for enabling the operator to position the sheet accurately in the machine.

There lis provided in the usual cylindrical platen a' series of gage-pins which may i project 'from' theA surface thereof, and may e-withdrawn or caused to disa pear so that their tips preferably will be ush wlth or form part of the writin .surface of the platen, to permit the emp oyment of thel platen for the usual purposes. These plus may be caused to project at the properA time when theplaten is in the proper position, and the operator.l may then introduce the sheet and set its leading edge against said ins. The pins are normally withdrawn;

ut by depressing the ke a trip or device-is set, which causes theA pins to project when the platen is turned to the proper point. Said key is preferably the same key that is usually rovided. for releasing the pressure rolls whlch run upon the platen. After the paper is introduced, the key is' returned to normal position, the pressure rolls hold the sheet to the platen, and the projecting gagepins are caused to disappear; A shaft is journaled within the laten and arranged to move the pins radial y of tlie platen. Said shaft is provided with an arm at one end of the platen, with which a spring-loek cooperates to retain the pins protruded. A stop is arranged near the end of the platen to be moved into and out of, positlon for p arresting said arm as the, platen is rotated,

and thereby turning said shaft against the resistance ofl a spring to cause .said shaft to protrndesaid pins to position such that they act as gage-devices for the s uaring of the paper inserted, the spring-loc for said arm engaging therewith at the same time. The further turning of the platen brings the spring-lock against a fixed can-which'. moves is an end view the lock-to release vthe said arm, and on releaslng the stop, the said arm snaps back v past its springlock,to its normal position,

and the pins are withdrawn into or flush with the surface of the platen.

In ,the accompanying drawings, Figure 1 is an elevation of a carriage with the laten in longitudinal section, andshowing t e invention applied thereto. Fig. 2 1s a perspective vlew, partly'in section, of the end of the carriage, platen and parts. Fig. 3 of the same,with the carrlage omitted. Fig. 4 is an end View of the same, but with the Aparts in-other positions. Fig. 5 is a similar view of the same, but in still other positions of the parts. Fig.4 6 is a front elevation of one position of the platen and appurtenances.'

The reference numeral 2 marks a 'carriage frame, in which the platen-shaft'S is mounted for rotation as usual. Numeral 4 marks the usual twirlers on the shaft 3. A rod or shaft 5 is journaled in the ends or heads 6 of 'the laten between the rod 3 and the tubular p aten body 7, and is provided with arms 8 fast thereon. spring 9 is coiled about the shaft 5 and the ends thereof bear against the inner surface of body 7 and the arm 8, respectively, said spring being tensioned to press said arms 8 toward the shaft 3. The arms 8 set loosely into slots 10 in a movable bar 11 inside the platen. A series of pins 12 projects from the side of bar 11 nearest the platen body 7, said pins extending vinto perforations 13 in said body or sheath, as shown, and being movable b the arms 8. The parts are so proportione and arranged, that when they are free to obey4 the bias of spring 9, the ends ofthe pins12 are preferably vflush with the. outer surface of the body 7 to form parts of the writing surface thereof. The'shaft 5 has an arm 14 fast thereon outside the laten, and the platen end 6 has a leaf spriiig 15, provided with av lock-lug 16 to engage arm 14 and the pins 12. protruded, asin Figs. 1 to 4. The lock-lug or part 16. has a face 17 to engage the upper edge (in Figs. 1 to 4) of the arm 14, for this purpoie.- Said spring 15 also has an inclined face or cam 18` for coaction with an arm or trip 19, fixed to the earrla-ge frame '2, whereby, in the rotation' of the platen in line-feeding direction, the arm4 19 cams or springs the spring 15 ltoward edge the incline 18 is.

the lat'eh end 6, to ielease armlfi, so that the atter may be swung by its spring 9, until arrested by the stop 2.0, on whose upperI 1The arm 14 1s preferably operated auto- 'matically during the rotation of the platen, -to protrude the pins 12, although it may be lerumed at`23, and connected by a link 24 with-an iarm 25 fast on a shaft 26, which is 'usually journaled in the: carriage 2, to releasez the usual pressure rolls 35, 35X.

On the rearedge of the link 24 is a lug '27 normally out of the circular path ofthe arm 14, but whichk may be moved into such path'by the voierationllof the lever 22, land when so move ,arrests the'free end of said arm 14 as th`e\-platen is turned as in linefeeding, so that `as the vplaten 4is 'further l turned, the shaft :5 will rotate independently,

projecting the'pins v12, 'and the spring 15 will move from thev position thereof shown in-Figs. 5` and 6, to the position thereof shown lin Figs. '1*to 4,-and 'will lock the arm 14 in position 'for "keeping the pins 12 in their protruded position, the rotation of the platen being arrested by the operator 'as soon las the-spring'l snaps over.

'The shaft' 26 aforesaid, is shown as notched at 26", so as 'to act as cams on the arms 28, v29.` The `arms 28 are integral with sleeves-30,'Which are loose on a rod 31, formin a partl ofthe Acarriage frame, and 32 are ot 'er varr'ns integral wlth or fast to said sleeves. The arms 32 yare provided with bearin s '33 for'the journals 34 of a pressurero ler 35,. Springs 36, fast to sleeves on rod 31,'act1to press said roller 35 against the platen. The arms 29 are integral with or rigidly attached to sleeves 37, lDoose on said rod 31,V and are provided with bearings 33x forthe journals 34x of a ressure rollery 35X, springs l36""fast to said s eeves 37, acting to :press said roller 35x against the platen. .The

normal positions of these parts are shown jinFig. 5. On pressing `down the lever 22 from the position thereof shown in Fig. 5 tothe osition shown in Fig. 4, the shaft 26 is 'given a quarter turn, and its notched parts 26x are turned from the vertical to the orizontal, thus forcing arms 28, 29 apart and'removing the rollers 35, 35x from contact with the platen, as shown in Fig. 4, and out of the paths of the pins l2. On the return of the lever 22 to its normal position, the shaft 26 is returned to the position there'- of shown in Eig. 5, and the springs named return the rollers 35,' 35x to contact with the platen.

When it is desired to insert pa er, the le' ver 22 may be depressed, as in iig. 4,v thus Aremoving the rollers 35, 35", from contact with the platen, and bringing 'the lug 2i' into the circular path of the arm 14.' rlfhe platen may now be turned in the direction of the line-feed motion'thereof, until lthe lug 27 has stopped the arm 14 long enough relatively to the moving platen, for the spring 15 to snap lock lug 16 above the arm 14 as shown, whereby the pins 12 are protr-uded from the'platenand are locked in suoli protruded position',^when the rotation ofthe platen is stopped by the operator. Then the paper p is inserted as shown `in Fig. 4, and its leading edge is brought againstthe gagespins 12, and while the paper is in' the described positiomthe lever 22 is snapped up, and the rollers 35, 35""are returned to their workin positions, asiliereinbefore set forth, and t epaper is caught, ready for feeding by rotating the platen. Then the platen is turned forward in the direction of its line-feed motion until 'the trip-arm 19, co-acting with the cam-surface 18, forces spring 15 so far toward the end 6 of the platen, that the arm 14 is released from the control thereof, vwhereupon the arm 14 passes upward alongside th'elock-lug 16 until arrested in'normal position bythe stop 20, and` the pins 12- are `withdrawn from their protruded positions. The paper 5 shelf 38 and guide-fingers 39 integral therewith are of known construction an'd opera-l tion.

Variations may be resorted to within'the scope of the invention, and portions ofthe improvements ma be used without others.
